Hose.

i To ellwho'm it 'may concern:

, ate eectively ner, and

Be it known vthat I., EDWARD J. CoUoHLrN, a citizen ofthe United States, residing in Passaic, county of Passaic, and State of New Jersey, have invented a newv and useful Improvement in Hose, of which. the following is a s ecification.

his invention relates to hose, and more particularly to hose for the transmission of steam and other heated fluids, and it has .for its principal object the provision of a hose for the purposes mentioned which is characterized by great durability and strength and is not liable to develop leaks in service,

f even when subjected to unusually high degrees of heat.

The object above mentioned and ot-hers which will hereinafter appear are attained in the hose. illustrated in the accompanying drawing and hereinafter described .and claimed. l

In the drawing, a lsingle dissected view, partly in elevation, and partly in section, lhows thel entire structure of the improved ose.

Referring to the drawing by the reference characters marked thereon, 1 designates the lining of the hose, which should be of a rubber compound adapted to withstand a high temperature and also characterized by a high degree of flexibility. This lining is formed upon a mandrel in any suitable man over it a jacket 2 -of asbestos is formed. This jacket 2 is preferably' made by a braiding process byl directly upon the tubular lining 1 while it is in position u on the mandrel1 a close union ol' the strancs of asbestos and the tubular lining 1 being thus obtained.\ The jacket 2 of asbestos isiseamless, and fits as snugly as possible around the lining 1 so as to copertherewith in resisting internal pressure. Surrounding the seamless jacket 2 of asbestos is placed a layer 3 of rubber co1npound,'which is brought into close association with the asbestos jacket and is formed in` any suitable manner directly over the asbestos acket. Surrounding the layer 3 of rubber which envelope vthe asbestos jacket 2, there is placed a strengthening sheath duck or other textile material, preferably cut on the bias, as shown, and wound around the layer 3 of rubber to form a wrapping prei lSpecification of Letters Patent.

senting a suflicient number of. lies to afford the degree of strength required) to resisty the internal strains andalso to effectively protectv the inner 'layers from injury from exter- 'lhe sheath 4 is preferably com# pletely covered byan outer envelop or jacket 5 of rubber, but-this outer jacket 5 may be made of any one of a number' of materials without departing from the spirit of the invention or it may, if desired, be omitted.

The hose constructed in the manner above described is especially serviceable, the asbestes jacket which surrounds the tubular lining contributingboth strength and heat# resisting qualities to the hose.v The seamless construction of the asbestos jacket 2 not only renders it stronger than a jacket formed .from a strip of asbestos cloth', lbut insures better union of the asbestos jacket with the lining of the hose, and it also insures the pr'otection of the layer `3 of rubberv and the sheath 4 of textile material from injurious effects from the heat of the steam or other fluid transmitted through the hose. The outer covering 5 of rubber serves its usual function of protecting the sheath 4 from mechanical injury and from the'detoriorating effects of air and moisture.

The hose above described, while of simple, compact, and comparatively light construe# tion, is adapted t0 withstand the effects of steam or other 'liuids at high temperature and correspondingly high pressure, and is particularly suitable for use upon railway trains, where the hose is subjected to most severe tests.

The invention having been thus described, what I claim as new is:

A hose structure comprising an inner tubular lining of vulcanizedv rubber compound, a seamless braided jacket of asbestos threads surrounding saidlining and in contact therewith, a layerlof vulcanized rubber compound covering said' jacket, and `a strengthening" and protective covering of textile fabric wound around said covering layer of rubber compound. o
